I found this method on another site, so this is not mine nor do I claim it to be

Special thanks to the (joy of Satan group) I will be trying this out tonight

Get real comfortable and go into a trance. When you are so relaxed you can no longer feel your body, you are ready.
Visualize your astral body inside your physical body, being held there by your seven chakras. The chakras can be visualized like colored knobs.
Take each spinning chakra and stop it from spinning and give it a quarter turn in the reverse of the direction it was spinning, like turning a doorknob.
Relax and let go and try to exit.
